Question

Can someone please help me out. I have a lot of math questions to do and I don't understand this topic. The question I need help with is attached. I would greatly appreciate it if someone could help me. Please

Answer 1

counterclockwise rotation about the origin of 270°

the coordinates of Q(6, 2), R(4, 9), S(2, 7)

the coordinates of Q'(2, - 6), R'(9, - 4), S'(7, - 2)

Note that the x-coordinate of the image is the y-coordinate of the original and the y-coordinate of the image is the negative of the x-coordinate of the original

This is a counterclockwise rotation about the origin of 270°

a point (x, y) → (y, - x) ← in general
